TGK 4" Intake With OEM Air Box Conversion For C7 Audi S6/RS6/S7/RS7

Introducing the TGK Motorsport Audi 4.0T Air Intake System, the ultimate upgrade for your 4.0T engine. Engineered with precision and crafted to perfection, this air intake system is designed to take your Audi's performance to the next level.

Specifically designed to seamlessly connect to the original C7 Airbox, this kit incorporates an OEM RS7 Filter. The Locking Collar utilizes a Billet Aluminum locking ring, which snaps into the factory air box, just like the factory piece.  It is important to note that it is not compatible with the factory S6/S7 Filter due to the smaller filter inlet size of the S6/S7 Filter.

At TGK Motorsport, we believe in pushing the boundaries of innovation, and the Audi 4.0T Air Intake System is no exception. It all starts with our meticulous flow tested design, developed from a 3D scan and transformed into a flawless 3D model. Countless design hours were dedicated to creating an intake system that delivers unrivaled performance.

The highlight of this system is the 4" Merged Inlet on the inlet side, allowing for easy installation by mounting to both turbos. No more hassle or complicated modifications—simply bolt on and experience the difference.

The TGK Motorsport Audi 4.0T Air Intake System is a complete package, including everything you need for a seamless installation. From the meticulously designed components to the comprehensive installation instructions, we've left no stone unturned in providing you with the best experience possible.

Flow Tested for Minimum Restriction & Max Velocity

We started by identifying the shortcomings of the factory intake system to determine which components restricted airflow to the turbos. We then focused on designing the inlet to function without restrictions by utilizing flow data.  We tailored the inlet design to accommodate the CFM required by the 4.0TT engine during Wide Open Throttle, and ultimately created in an intake that sounds and performs better than stock.

Louder Induction Noises! 

Per the design, both turboes are pulling through a single filter. In turn this creates extremely loud induction noises!
